I’d say that Vault - File - Obsidian is best for me, since Vault is what differentiates the windows. The file is good, but I can change it in one click - I can’t change my Vault without opening a new window, so that’s what I want to be aware of without having to click.
Moreover, not sure how it would work technically to add file name; since you can split your window in several panels with each one file, would it rename the window everytime you move from one corner to another?
